Brucella abortus RB51 induces protection in mice orally infected with the virulent strain B. abortus 2308.
Brucellae are gram-negative, facultative intracellular bacteria which are one of the most common causes of abortion in animals. In addition, they are the source of a severe zoonosis. In this trial, we evaluated the effect of oral inoculation of Brucella abortus RB51 in mice against a challenge infection with B. abortus 2308. First, we showed that a gastric acid neutralization prior to the oral ...
متن کاملSafety of Brucella abortus strain RB51 in black bears.
In two studies conducted from October 1999 to March 2000 and December 2000 to April 2001, adult black bears (Ursus americanus) were orally inoculated with 1.4-3.1 x 10(10) colony-forming units (CFU) of Brucella abortus strain RB51 (SRB51, n=12) or 2 ml of 0.15 M NaCl solution (saline, n=11). We did not detect a difference (P>0.05) in antibody titers to SRB51 in serum obtained before vaccination...
متن کاملBrucella abortus RB51 and hot saline extract from Brucella ovis as antigens in a complement fixation test used To detect sheep vaccinated with Brucella abortus RB51.
The efficacy of Brucella abortus RB51 and hot saline extract (HSE) from Brucella ovis as antigens in complement fixation (CF) tests was comparatively evaluated in detecting immune responses of sheep vaccinated with B. abortus strain RB51. For this study, four 5-month-old sheep were vaccinated subcutaneously with 5 x 10(9) CFU of RB51, and two sheep received saline. Serum samples collected at di...
متن کاملThe Assessment of Cytokine and Antibody Responses to Recombinant 31kDa Brucella Cell-Surface Protein in Brucella Abortus Infected Mouse Model
Background & Objective: One of the most common diseases between zoonosis - especially in developing countries – is brucellosis. Identification of Brucella cell antigen combinations in terms of the amount and type of immune response in infected hosts, are important in vaccine design. 31kDa Brucella cell surface protein (BCSP31) is shared among all Brucellae. We aimed to define specific immune r...
متن کاملImmune Response of Calves Vaccinated with Brucella abortus S19 or RB51 and Revaccinated with RB51
Brucella abortus S19 and RB51 strains have been successfully used to control bovine brucellosis worldwide; however, currently, most of our understanding of the protective immune response induced by vaccination comes from studies in mice. The aim of this study was to characterize and compare the immune responses induced in cattle prime-immunized with B. abortus S19 or RB51 and revaccinated with ...
